This course studies the analysis of forces acting on particles, rigid bodies, trusses, frames, and machines in static equilibrium with applied forces and couples. Topics covered includes force vectors, equilibrium of a particle, equivalent systems of forces, equilibrium of a rigid body, structural analysis, internal forces, friction, analysis of the equilibrium of rigid bodies subjected to fictional force, centroids and moments of inertia. 3 hours of lecture and 2 hours of laboratory per week. Prerequisites: PHEN 121. Co-Requisite: MATH 200.
